[Features] - Zlok (Gazette lock)® is a mechanical type of pipe joint that was developed for stainless steel piping. - It is a reliable joint which is excellent in corrosion resistance and heat resistance, utilizing the light and strong characteristics of stainless steel piping. - It has a structure in which proper surface pressure to the packing provides stable sealing performance over a long period of time. - The packing is excellent in durability, heat resistance, and salt-containing water resistance and uses fluororubber material that meets the leaching standard when used for a water supply system. - It is tightened by a nut for each connection portion of the pipe and fittings in the tapered surface and a strong connection force is obtained by the so-called wedge effect. - Packing does not need to be removed from the joint at the time of the piping. - In addition, since it cannot be used for piping without performing expansion processing of the tube end, problems such as pipe supports coming off are avoided. - With the unique indicator that makes it easy to distinguish between hand tightening and actual final tightening, you can easily confirm whether or not you have forgotten to tighten the pipe fully. - If you forget final tightening, leakage might occur from the joint portion at the time of a water pressure test; forgotten tightening can be detected. - Expansion is done automatically by a machine so accurate pipe setting is easy achieved. - Since the connection portion of the pipe and fittings are less likely to wobble, it is easy to support and fix the pipe.
